How to find out Cisco 877 Mac Address

Peter Sheridan

Hello,

I have recently had to rebuild the cookie information for a cisco 877 series router due to it being erased by an electrical surge.

I've successfully got it running again by copying the cookies from an identical router (obviously changing the serial numbers and so forth so it passes its verification checks).

The last piece of information I need is the Chassis MAC Address. I don't want to use the one from another router since there will probably be conflicts.

I tried following this Field Note, even though it isn't specifically for my model and it didn't work.

http://www.cisco.com/en/US/ts/fn/200/fn25254.html

Does anyone know how I can get the mac address from the system somehow?

Any help is appreciated.

Cheers

Peter Sheridan

Hi Jose,

Thanks for your reply. Unfortunatly that will only show me the mac address i've manually put in, when recreating all of the cookies.

It doesn't show me the original one that would have been assigned when the board was manufactured.
